7 i) all whom. it may concern:

Be it known that I. Homes C. Lns'rr. of (ushing, in the county of Payne and State of Oklahoma; have invented reri'uin new and useful improvements in (Ml-Refining Apparatus; and I do hereby declare the following to be a full. clear. and exact description of the invention, such as will enable others skilled in the art to .which it uppertuins to make and use. the. sumo.

My object is to provide improved menus for separating gusoleue from (rude oil and utilizing the heat.- obtained. and saving: fuel oil and gus and increasing capacity. The

' preferred 'l'orm of embodiment of my invention is conventionally illustrated in the 2U'- (:ompanying drawing,

[is illustrated. 1. 2. 3 and l are stills. still i being supplied with crude oil from a separutor 5. 4

A heater pipe 6 is shown connected at one cud with u pipe 7 leading from still i and at the. other end with :rfuel pump 8. A alve is shown in pipe 7. Inside oi Plpu (l is shown a series oi tubes illeudiug from u crude oil pump 10 to separator 5. More. specifically the tubes 9 enter manifolds l2 and 18 which, by single pipesll. 15. are

connected.respectively. with the crude oil pump 10 and separator 55.

The separator 5 isadapted for connection with a condenser audit, is shown receiving the pipe 15', a pop valve 16 being arranged in the pipe outside of the separator und normally set at t e-7O lbs. Inside tho separator at i-he. point of introduction of pipe 15 is arranged 2i. concuvcd deflecting pan 1?. Above this pan and in line toward the exit to the condenser is a series of oatlie plates 18. 19 is the-pipe leading from the so amt/or to still 1.

n operation the suction pump 8 draws the fuel from still 4 at about 600 F. through pipes 7 and 6. At. the same time the pump 10 forces crude oil through pipe 14 and tubes 9 and pipe 15 to the separator 5. During its passage through tubes 9 the oil is heated to ahout 500 F. by the heat; given up to it by the fuel. in pipe 6 and the fuel is correspondingly cooled. When the oil roaches valve 16 under about 60 lbs. pressure and is admitted to the separator 71 and contacts with pen 17..tho crude oil is atomized and-in passing in contact; with the. bafilo plates the heavier fuel is separated from the gasolene which passes oil? to u condenser.

The reduced crude oil then passes from the separator through pipe 19 to still 1. No

separate heating means is required for the separator. But little heart is necessary in i tills 1, 2 and 3. Still i requires the greatest ieur.

It will be noted chat the maximum elliciency of the heat is thus made use of; that. the fuel oil is cooled down while the crude oil is being heated. thus insuring an economy of heat and an increase in production of gusolene. I attribute special importance to the ntomizing actionefi'ected by the pan 17. I

it 20 l have shown what. I term on equalizer. This may be constructed like the heater pipe 6 end is showri in the form of a pipe. in communication with pipe 7 and controlled by rah-e21. This equalizer mayreceive a portion of the oil from still 4 and thereby regulate the heat entering the heater 6 and thus control the gravity of the. gasolcne and benzene leaving the Separator 5 in the form of a vapor. 23 is the separator Which is included in'the equalizer sys tem and. like separator 5, may lead to a condenser. 24 is a fuel pump to which pipe 20 leads and 25 is a naphtha. pump from which tubes 26 pass through pipe 20, simiiur to the. relative arrangement of tubes 9 and pipe 6. The equalizer thus performs two functions. It governs the oil fed to the heater ipe 6, and it utilizes what would be excess out, in 6 fordistilling nuphthas and light oils.

I claim as my invention:

l. ln m oil separator, u still, a. suction pump, a pipe conducting oil from said still to said pump. a separator. a. plurality of inbes within said pipe ind extending throughout the length thereof, and a single said sepapipe leading'from said tubes to ruior.
